BAILRDAD-GAE HEATER'.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN RICE, of l loomington in the county of Monroe,and State of Indiana, have invented a newr and useful Car-Heater; and Ido hereby declare that the following is a full and` exact description ofthe same, reference being had to the accompanying drawings, and to theietters of reference marked thereon.

This invention relates to `certain improvements in heatingapparatus for'railroad-cars, and consists princivpally in the construction andarrangement oi' the heater, as will be fnllydescribed hereinafter.

Figure 1, sheet 1, represents a side elevation ci' one form of myimproved beater.

Figure 2a plan view of thesame.

'Figure 3, a sectional view of the flexible joint.

Figure 4, an elevation of the pipe-coupling, unccnpled.

Figure 5, sheet 2, represents a side eleva-tion -oi' another form or myheater,and

Figure 6 a plan view ol` tbesame.

In the drawings, sheet 2, A represents an iron box or chamber, which issecurely attached beneathl the car, above the trucks. This box should bemade sufficiently strong to prevent the trucks from forcing themselvesup through the floor of the carin case of accidenti.

B represents the fire-box proper, which is attached below box A, atitscentre, as shown. This re-box is constructed with double walls anddoors, for the purpose of shutting in the heat, and preventing theEre-box from beingcoolcd by its rapid motion. It is also provided withsuitable openings for draught upon each side,

" which have, of course, regulating-dempers, which latter may beoperated from the car by any proper leverarrangomcnt. The iirc-box isdivided into two parts, being separated by the chamber I, inWhichvlatter water maybe placed for the purpose of giving the heated airproper moisture. 'This chamber is covered with. an iron plate, whichseparates it suitably from thc other partsof the heating-apparatus.Openings, however', should be left, topermit the steam to rise and passinto the other parts. l

Opening into it, above the plate, upon either side, are the air-tubes DD, which extend in either direction, and communicate with the hotairchambers E E, one being located at each end of the our.

C C represent chambers communicating withthe chambers of the iire-bcxbelow. These are also covered in with iron plates, to shut-'oli`communication with other parts of the apparatus. Gpening intotnese alsoare the smoke-tubes F F, encirclingV the air-tubes D D, which formercommunicate with the smoke-chambers G G. It will also be observed thatthe air-tubes pass across these chambers, and thus-eccixfe heatdirectlyfrom the re below. Being also surrounded bythe tubes whichconvoy away/,the smoke and products of combustion, they retain theoriginal heat, and constantly receive frcshsupplies from this source.

H H represent passages out through the smoke-tubes into the air-tubes,for` the purpose of tappingthe latter, and obtaining a supply of heatedai" at'any desired point.' i

I represents an iron plate covering the entire heating-apparatus.

z' represents the-smokespipe holes communicating with the chamber below.

i12" represent the cold-air entrances, which opcn'into chambers B below.

il 1? represent registers over the hot-air chambers, and 1,'3 t,registers over the openings H H.

It will be observed that, by the general arrangement before described,two large chambers are formed, JJ, around the smoke-tubes F F. In thesealso the air must necessarily become very much heated. This may beutilized by simply having a register open into it. The register t,placed over passages II Il, may be set a little distance above thetubes, which arrangement will allow the heat from chambers J J to passout with the heat from the air-tubes.

In street-railway cars it may be desirable to make and tend.the lirewithin the car, in which case suitable doors should be made in theexterior plate, I, and interior plate over the fire-chambers.

The operation of my invention is es follows:

The tire is built in the tire-box B, either from above or below, as thecase may be, and water is placed in chamber B. Cold air is admitted'through the entrances i151, which open into the chamber B below. Uponentering thisl chamber', the cold air unites with the steam rising fromthe water below, thus receiving proper moisture, and passes into tubes DD, upon either side.

The first part of these tubes passes through the fire-box, and is highlyheated thereby, which heat, being communicated to the air, is retainedby it in its continued passage through the tube, the air being stillfurther heated bythe hotgas and smoke in pipes F, which surround pipesD.These tubes may be extended the entire length of the car, it` desired.

By this arrangement the air is heated to a very high temperature by thetime it lreaches the chambers E E. From there it is drawn ofi` by meansof registers. Passages may becut through the smoke-pipes, andtheair-pipes tapped at any desired point, so that, if considered necessary,a register may be placed at every seat. The smoke and products ofcombustion arising from the tire-box, pass through the smoke-tubes, asdescribed, into smokechambers G G, and are discharged finally throughthe smoke-pipe il.

The air-pipes may be extended with the smoke-pipes, if desired, and becarried with them up the sides of the car, in which case they may betapped at both top and bottom, if desired'. Suitable openings in theouter box may be made, for the purpose of cleaning the tubes, whennecessary. If desired., an additional pipe may be placed about thesnmke-pipe, to insure a more perfect retaining of the heat. This,however, is not deemed necessary ordinarily. The air and smoke-tubeswill necessarily expand more or less under the influence of the heat,and it is therefore proposed to make the partitions free at one end, i'norder that they may slide forward when the tubes expand, and backwardwhen they contract.

In sheet No. l is shown a modiiication of my invention, and also themanner of conducting the heat from car to car.

In the drawings, I( represents an iron box, which may be securelyattached beneath the floor of a baggagecar, or other suitable place.

K represents the re-box proper, which may be fired from above or'bclow,as desired.

L represents the air-tubes, which may open into a chamber provided withsuitable outward openings, or they may communicate with the open air.These tubes pass directly through the tire-box, and also through thesmokepipes, as previously described.

L1 represents the hot-air chambers, with conductors L2.

M represents the smoke-tubes, M1 the smoke-chamber, and M2 thestroke-pipes.

N N11 N2 representithe pipes which conduct the heat from car to car.- N3represents the flexible joint, and N4 the coupling. The Ijoint iscomposed of the socket n and ball nl, the latter of which is providedwith the groove u2, in which packing is inserted.

The pipe is smaller in size'than pipe N. This allows the joint to morefreely to some extent, without v permitting the escape of the heatedair.

The coupling consists of the pipe l, which is provided with the groovedand packed head or, which fits snugly into pipe l 2, the latter beingprovided with the enlarged opening, as shown, for the purpose ofpermitting the connection to be easily made. These different pipes areof sulhcient length' to permit .the pipe Nl to play forward and back inthe pipe In without danger of disconnecting.

'lhe disconnection is easily made when the cars uncouplc, as the pipe N1simply draws'out of the pipe N2. It deemed necessary, these pipes may bealso made double, for the purpose of more perfect-ly retaining the heat.

The apparatus herein described may be used in summer as a ventilator,for which purpose it is exceedingly well adapted. i i

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

'ihe heating-apparatus A B, constructed and arranged as described, thatis, having the chamber B, air-tubes D in smoke-tubes F, chambers C C, EE, G G, and registers and discharge-pipcs, asshown, the whole beingattached to and combined with a railroad-ear, and operatingsubstantially in the manner described, and for the purpose set forth.

vThis specification signed and witnessed, this sixteenth day of May,1868'.
